Tomei - SR20DET VALC Poncam Camshaft - S14/S15

New for 2018, Tomei Poncams for all S14/S15 SR20DET models. Because they are designed to be compatible with stock valve springs and 'bolt-on' type turbos, Tomei Poncams are the best drop-in camshaft solution for the SR20 powertrain.

Utilizing cutting edge VALC profile technology, the Poncam 258* camshafts combine the stable idling and low midrange of a 256* camshaft together with the top end performance of a 264* camshaft. In addition, they also feature the highest lift amount that's compatible with the stock valve springs for increased flow rate and higher power output.

Tomei also offers the PROCAM, designed for use with large turbo setups and high RPM use. The PROCAM can be found HERE.

VALC Valve Lift Profile _{Velocity, Acceleration, Lift, Control}

The new VALC profile allows the valves to open faster and for longer. This translates to faster lift and increased area under the 'lift curve' which in turn generates more power. (Greater area under the 'lift curve' = increased air intake.)
